Seki-kun starts playing Go on his desk. Yokoi-san tries to ignore this since she doesn't know the rules, but this yet again turns into something rather unexpected.
A new enemy?! And it's the opposite color!
Ein neuer Gegner?! Mit invertierten Farben!
¡¿Un nuevo enemigo?!
Un nouvel adversaire !
Un nuovo nemico?! 
Con i colori invertiti!
Um novo inimigo? E da cor oposta!
